反应堆下腔室结构优化设计

Optimization Design of Reactor Lower Plenum

对目前现有的反应堆下腔室结构的不足进行优化分析,针对性地提出解决措施。分析中重点从下腔室结构的稳定性、可靠性和流场的不均匀性入手,采用简化结构和计算流体力学(CFD)计算下腔室流场,使反应堆下腔室具有结构简单、稳定可靠、流场均匀等特点。

Characteristics of the reactor lower plenum are analyzed by CFD, which are focused on the stability and reliability of structures and the equality of the flowing. After refinements and improvements, better reactor lower plenums are got, which are simple, stable and equability flowing.
